#' @title Get All Concept_ids In All Event Tables.

#' @description This function gets the unique concept_ids in all event tables.

#' @param connectionDetails  An R object of type\cr\code{connectionDetails} created using the
#'                                     function \code{createConnectionDetails} in the
#'                                     \code{DatabaseConnector} package.
#'
#' @param cdmSchema  The name of the database schema that contains the CDM.
#'                   Requires read and write permissions to this database. On SQL
#'                   Server, this should specify both the database and the schema,
#'                   so for example 'cdm_instance.dbo'.
#' @param cdmVersion The version of your CDM.  Currently "5.3.1" and "5.4.0".
